HYBRID GEOMETRIC CALIBRATION METHOD FOR MULTI-PLATFORM SPACEBORNE SAR IMAGE WITH SPARSE GCPS
SAR image geometric calibration R-D model multi-platform TerraSAR-X TanDEM-X Gaofen-3
2018/5/15
Geometric calibration is able to provide high-accuracy geometric coordinates of spaceborne SAR image through accurate geometric parameters in the Range-Doppler model by ground control points (GCPs). H...
A RAPID METHOD FOR WATER TARGET EXTRACTION IN SAR IMAGE
Synthetic Aperture Radar Imagery Water Target Automatic Recognition Grey Morphology Nonlinear Filter
